I just (yesterday) passed my Google Cloud Certified - Professional Cloud Architect exam.
It has been a long and quite hard way until achieving this, and the Linux Academy courses have been a really valuable resource. Thanks to all the great explanations of Matthew I could focus on the most important sections, and I got some questions quickly answered withouth thinking thanks to the tips he provided during the course.
To all the other brave ones out there:
- This is a difficult exam, but it IS achievable. Keep going!
- The exam is a mile wide and an inch deep... but sometimes you may find a deeper hole. Pay attention to the details and WORDING of the questions and most of the times you can discard 2 of the answers, even on those questions you initially may not have a clue.
Reviewing the case studies is fundamental, I got around 10 questions based on the THREE cases, so 1/5 of my grade was directly dependant on the case studies.
Get hands-on practice on GCP (DO THE LABS!) and read all the documentation you can. I recommend reading the best practices docs for the services and products.
- Networks: Cloud VPN/Router. You think you know it? Good, now go back and study it all again (and practice it). Are you done? Do it again.
Finally, for those willing to go the extra mile, if you have enough time (and can afford it) Google also provides their own online (paid) training courses and some extra resources.
- The Linux Academy courses are a great direct and complete approach to GCP, clearly focused on learning and building using the main tools from GCP, specially those that will be covered on the real exam. If you are preparing for the certification or are on a tight schedule to come to grips with GCP, the LA courses from Matthew are perfectly suited. However, some very obscure details that may appear in a few exam questions will not be directly covered in the courses, and will require you studying the Google documentation.
- The official Google course will provide you with a thorough comprehension of all GCP. It is really valuable for getting the most out of every service and is really good at setting your mind towards how to design and architect for the cloud, BUT is not the best to prepare solely for the certification (tons of info and practice, not exclusively focused on the exam) and takes quite some time to complete and digest it all.
- Although may not seem directly related, if your goal is learning how to become a great architect (and you are a lucky one with plenty of time), read the SRE book (https://landing.google.com/sre/) that will give you a great view about how to make things "the Google way". There is a free book (theory) and a paid one (practice).
Good luck to everyone!
